+# Docker Setup for Pi-gen Builds
+
+## Current Situation
+
+You need Docker access to build Raspberry Pi images, but you're not in the `docker` group.
+
+## Quick Fix (Requires Admin)
+
+**Ask someone with sudo access to run:**
+
+```bash
+sudo usermod -aG docker work
+```
+
+**Then YOU run:**
+
+```bash
+# Refresh your groups (pick one)
+newgrp docker           # Option 1: New shell with updated groups
+# OR
+exit                    # Option 2: Log out and back in
+```
+
+**Verify it works:**
+
+```bash
+docker ps               # Should work without "permission denied"
+```
+
+## Current Docker Group Members
+
+```
+docker:x:984:michael
+```
+
+User `michael` is in the docker group - they may be able to help or know who can.
+
+## After Docker Access is Granted
+
+You can then build your image with:
+
+```bash
+cd /home/work/pi-gen-builder
+./build-docker.sh
+```
+
+Or use the helper script:
+
+```bash
+cd /home/work/dangerous-pi
+./build-image.sh full
+```
+
+## Alternative: GitHub Actions (No Local Docker Needed)
+
+If you can't get local Docker access, we can set up automated builds using GitHub Actions.
+
+### Advantages
+- ✅ No local Docker required
+- ✅ Free for public repos
+- ✅ Builds run in the cloud
+- ✅ Automatic on every push
+- ✅ Download built images as artifacts
+
+### Setup
+
+Would create `.github/workflows/build-image.yml` that:
+1. Checks out your code
+2. Runs pi-gen build in GitHub's Docker environment
+3. Uploads the resulting image as a downloadable artifact
+
+**Build time**: ~1-2 hours in GitHub Actions
+**Cost**: Free (public repos get 2000 minutes/month)
+
+Let me know if you want me to create the GitHub Actions workflow!
+
+## Alternative: Cloud VM (Temporary)
+
+If you need to build NOW and can't wait for permissions:
+
+### Option 1: Oracle Cloud (Free Tier)
+```bash
+# Create free ARM VM
+# SSH in and run:
+git clone https://github.com/RPi-Distro/pi-gen.git pi-gen-builder
+cd pi-gen-builder && git checkout arm64
+# Copy your files and build
+```
+
+### Option 2: DigitalOcean
+```bash
+# $5/month droplet (destroy after build)
+# Similar setup
+```
+
+### Option 3: AWS EC2
+```bash
+# t2.micro (free tier eligible)
+```
+
+## Summary
+
+**Fastest solution**: Ask someone with sudo to add you to docker group (1 minute)
+
+**No-permission solution**: GitHub Actions (30 minutes to set up, then automatic)
+
+**Alternative**: Build on cloud VM (requires account setup)

+**Current Status**: ⏸️ Waiting for Docker group access
+
+**Blocker**: Need `sudo usermod -aG docker work` to be run
+
+**Who can help**: User `michael` or system administrator
